1.config 模块

 1 import configparser
 2 
 3 conf = configparser.ConfigParser()
 4 conf["DEFAULT"] = {ServerAliveInterval: 45,
 5                       Compression: yes,
 6                      CompressionLevel: 9}
 7 conf[wwwwwwwww] = {}
 8 conf[wwwwwwwww][user] = baidu
 9 conf[topsecret.server.com] = {}
10 topsecret = conf[topsecret.server.com]
11 topsecret[Host Port] = 50022
12 with open(conf.ini,w) as f:
13     f.write(conf)

2.hashlib操作

1 import hmac
2 h = hmac.new(bhsc)
3 h.update(b12233)
4 print(h)

 

3.random模块

 1 import random
 2 print(random.random())
 3 print(random.randint(1,2)) #0,1,2  随机
 4 print(random.randrange(1,2))#0,1   随机
 5 
 6 checkcode = ‘‘
 7 for i in range(6):
 8     current = random.randrange(0,6)
 9     if current != i:
10         temp = chr(random.randint(65,90))
11     else:
12         temp = random.randint(0,9)
13     checkcode += str(temp)
14 print(checkcode)

 

4.shelve模块

 1 import shelve
 2 
 3 d = shelve.open(shelve_test)
 4 
 5 def stu_data(name,age):
 6     print("register stu",name,age)
 7 name = ["hsc","xjp","abm"]
 8 info = {"name":"hsc","age":18}
 9 
10 d["test"] = name
11 d["info"] = info
12 d[func] = stu_data

 

5.shutil模块

1 import shutil
2 
3 # f1 = open("random mod .py")
4 # f2 = open("random_new .py",‘w‘)
5 # shutil.copyfileobj(f1,f2)
6 
7 # shutil.copyfile("笔记",r‘d:\123‘)
8 shutil.make_archive(www,gztar,root_dir=rC:\Users\heshaochuan\PycharmProjects\py_s15\day6)

 

6. logging模块

1 import logging
2 
3 log_test = logging.getLogger(TEST)
4 logging.basicConfig(filename=wwwwwwwwww.log,level=logging.INFO)
5 logging.debug(mthgh)
6 logging.info(2131234324)

7.re模块

常用正则表达式符号

‘.‘     默认匹配除\n之外的任意一个字符,若指定flag DOTALL,则匹配任意字符,包括换行
‘^‘     匹配字符开头,若指定flags MULTILINE,这种也可以匹配上(r"^a","\nabc\neee",flags=re.MULTILINE)
‘$‘     匹配字符结尾,或e.search("foo$","bfoo\nsdfsf",flags=re.MULTILINE).group()也可以
‘*‘     匹配*号前的字符0次或多次,re.findall("ab*","cabb3abcbbac")  结果为[‘abb‘‘ab‘‘a‘]
‘+‘     匹配前一个字符1次或多次,re.findall("ab+","ab+cd+abb+bba") 结果[‘ab‘‘abb‘]
‘?‘     匹配前一个字符1次或0
‘{m}‘   匹配前一个字符m次
‘{n,m}‘ 匹配前一个字符n到m次,re.findall("ab{1,3}","abb abc abbcbbb") 结果‘abb‘‘ab‘‘abb‘]
‘|‘     匹配|左或|右的字符,re.search("abc|ABC","ABCBabcCD").group() 结果‘ABC‘
‘(...)‘ 分组匹配,re.search("(abc){2}a(123|456)c""abcabca456c").group() 结果 abcabca456c
 
 
‘\A‘    只从字符开头匹配,re.search("\Aabc","alexabc") 是匹配不到的
‘\Z‘    匹配字符结尾,同$
‘\d‘    匹配数字0-9
‘\D‘    匹配非数字
‘\w‘    匹配[A-Za-z0-9]
‘\W‘    匹配非[A-Za-z0-9]
‘s‘     匹配空白字符、\t、\n、\r , re.search("\s+","ab\tc1\n3").group() 结果 ‘\t‘
 
‘(?P<name>...)‘ 分组匹配 re.search("(?P<province>[0-9]{4})(?P<city>[0-9]{2})(?P<birthday>[0-9]{4})","371481199306143242").groupdict("city") 结果{‘province‘‘3714‘‘city‘‘81‘‘birthday‘‘1993‘}
